Why are Bowers and Wilkins so expensive?

I've often wondered, why do Bowers and Wilkins speakers come with such a hefty price tag? Is it just the brand name, or are there specific features and technologies that justify the cost? Are the materials used of a higher quality than other manufacturers? Or is it the sound quality that truly sets them apart, giving them a premium feel that's worth every penny? I'd love to know more about what makes these speakers so special and what factors contribute to their high price point.
